Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Sodium nitrate (CAS 7631-99-4), also called Chile saltpeter, is an inorganic oxidizer. HSDB documents its use in fertilizers, as the oxidizing component of explosives and blasting agents, as an oxidizer and fluxing agent in glass and enamel manufacture, and in the production of nitric acid and sodium nitrite. It also serves as a color fixative in cured-meat processing and as a heat-transfer salt.
Frequently Asked Questions
What is sodium nitrate USP granular used for?
Sodium nitrate (CAS 7631-99-4, also called Chile saltpeter) is an inorganic oxidizer used as an oxidizer and fluxing agent in glass and enamel manufacture, as the oxidizing component of explosives and blasting agents, as a feedstock for nitric acid and sodium nitrite, as a component of molten-salt heat-transfer media, and as a color fixative in cured-meat processing. RawSource supplies USP granular grade for these industrial and processing applications.
What is the difference between USP granular sodium nitrate and technical grade?
USP grade is manufactured to United States Pharmacopeia purity and identity specifications, with tighter impurity limits than technical/industrial grade; granular refers to the physical particle form. Choose USP where pharmacopeial specifications are required and technical grade for general industrial oxidizer use. Request the CoA to confirm the grade meets your specification.
What is the molecular formula and CAS number for sodium nitrate?
Sodium nitrate is NaNO3 (NNaO3), CAS 7631-99-4. RawSource provides a CoA confirming assay, particle form, and specifications for each lot of USP granular material.
How is sodium nitrate shipped, given that it is an oxidizer?
Sodium nitrate is assigned UN 1498 (oxidizing solid) for transport; DOT/IMDG shipping must follow the requirements for that hazard class, and RawSource ships in compliant packaging with the SDS. It is supplied granular in bags, drums, and bulk. Request the SDS for handling and transport documentation.
How do I get a bulk quote for sodium nitrate USP granular?
Bulk pricing depends on grade, volume, and packaging (bags, drums, supersacks, or pallet quantities). Contact RawSource with your required grade and volume for a current bulk quote, CoA, and SDS.
